agentStep( Agent agent, Helipad model, int stage )

Runs when the model activates an agent. The main logic of an agent-based model should be hooked here.

This hook generalizes to [primitive]Step, e.g. the step function of an agent with primitive 'bank' would be hooked with bankStep. To hook the step function of agents of all primitives, use baseAgentStep.

The list of agents to be stepped is finalized at the beginning of each stage, so any agent who is alive at the beginning of the stage will be stepped, even in the unusual case that it dies between then and its actual stepping. If this is undesired, if agent.dead: return at the beginning of the hook will prevent this.

Required Parameters

• agent — Agent

  The agent being activated.

• model — Helipad

  The model object.

• stage — int

  The current stage of the model. For single-stage models, this parameter will always pass 1.
